As much as personally I'd love them to be included (it would make my life a whole stack simpler) I can't see it happening in a hurry. Firstly, whilst the "community" spread is very low in SG (hovering around 10-20/day) they have to get their dormitory situation under control before AU or NZ should consider opening the borders. But more importantly, in the longer term SG needs foreign workers to keep anything vaguely similar to current living standards, this includes Bangladeshi/Indian/Sri Lankan/Nepali/Chinese construction workers, Chinese bus drivers, Malaysian workers (commuters) across all sectors, Filipino and Indonesian domestic helpers and Filipino hospitality workers and nurses. Longer term the country will be screwed if they can't find a way to continue to import workers for low level jobs, and that may mean AU/NZ have to keep the borders closed. Although quarantine on arrival, for all but the Malaysian commuters, is definitely achievable.
